Write short notes on Charts.

Charts are visual representations of data or information, typically using symbols and colours to display relationships, trends or patterns. They are represented through X-axis and Y-axis with at least one numerical value on one of the axes. Charts help simplify complex data for easier understanding and analysis. Common types of charts include Line Chart (for trends over time), Bar Chart (for comparing categories), Pie Chart (for showing proportions of a whole) and Histogram (for showing frequency distributions).
